' COMPOSITION FOR REMOVING PAINT AND VABNISH.

No Drawing. Application filed July 14,

This invention relates to a composition of matter for removing paints, varnishes and the like from various materials.

The primary object of the invention is provide an improved composition which will more readily and perfectly remove pamt, varnish and like stains, and to a process for manufacturing such a remover, which 1s sunpler' and more efliciently carried out than those heretofore used.

Another'object of the'invention is to provide an improved aint and varnish remover of'a consistency of preferably aheavy syrup which can be applied with a brush and thereafter easily removed with a sponge or by playing a hose thereupon.

, Another object of the invention, is the provision of; an improved and simple process for manufacturing a paint and varnlsh re mover, such process requiring no heatmg and comprising sim ly the thorough dissolving and mixing 0 certain ingredients in cold water to form a syrup-like solution.

With the above and other objects in view, my invention consists in the novel product herein defined and the novel method of pro,- ducing such product. It should be understood, however, that while I have herein defined one speeifi'c method for carrying. out my invention, such method can be varied as defined in the appended claim.

The several ingredients which may be used are as follows, but it will be seen that all of such ingredients are not essential to the practicing of my invention:

Three pounds potassium hydrate,

One pound ammonia,

One-half pound corn starch,

Three quarts of water,

One-half pound of ether,

Three ounces of citronella,

Three teaspoonsful of burnt sugar.

Briefly my improved method, 111- its pre ferred form, is as follows:

I thoroughly dissolve three pounds of potassium hydrate in one-half gallon of cold water. I dissolve one-half pound of starch, preferably corn starch, in one quart of cold water. I then combine these two solutions,

at the same time stirring the same rapidly 1924. Serial no..'z25,ase.

for about two minutes assure a thorough mixing thereof. Into this product I add one pound of ammonia (preferably about 12 per cent) and stir sufliciently to thoroughly mix the entire ingredients together. The'resulting product will be a heavy syruplike solution which will most eiiiciently rei sugar may be added to the solution to give the same a desirable odor and color, respectively.

.As above stated the product in its-final and usable form is preferably of a heavy syrup-like consistency. This form of the product is advantageous for various reasons. Primarily among these is its easy applica tics in use. This operation is very sunple an consists of merely applying the p with a brush to the surface to be trz i d d. This coating-should be permitted to remain on the surface for about thirty minutes, during which time it acts on the paint or varnish to dissolve and absorb the same. The syrup can theieaftier be easillyl remgltalved with a sponge or y p'ay' a ose t ereu 'fn. When thus removedl tiie surface found to be entirely free from the-{objectionable stains. It may furthermore be stated that in its liquid form the remover can be easily bottled and placed in salable condition.

Having thus described my invention, what I claimand desire to secure by Letters Patent is A composition for removing paint and varnish, consisting, approximately. three pounds of potassium hydrate, one pound of ammonia, one-half pound of corn starch one-half pound of ether, and three quarts. of

water in solution.
